What is it about?
A shock interacting with a bidisperse particle curtain gives rise to complicated physics due to turbulence, compressibility effects, interparticle collisions, and strong coupling between the solid and gas phases. We propose a scaling law for "segregation rate" defined as the ratio of the average displacement of the small particles to that of the large particles. Important statistics of particle curtain spread and particle volume fraction evolutions are presented.

Why is it important?
Research efforts into high-fidelity simulations of bidisperse flows with large diameter size ratios are limited. We explore very high size ratios in the context of high-speed compressible flows accounting for physics across wide time- and length-scales. We propose scaling laws to collapse segregation rate across parameters of shock Mach number, particle volume fraction, and diameter size ratios.
